Description
Schachttrockner mit einer Mehrzahl neben- und übereinanderliegender, innen und außen beheizter Trockenwalzen. Die Erfindung betrifft einen Trockenofen, bestehend aus einem doppelwandigen Schachtgehäuse, in dem eine Anzahl Trockenwalzen neben- und übereinander eingebaut sind, welche sowohl von innen als auch von außer. beheizt werden.Chute dryer with a number of adjacent and superimposed, inside and outside heated drying rollers. The invention relates to a drying oven, consisting of a double-walled shaft housing in which a number of drying rollers are installed next to and on top of each other, both inside and outside. be heated.
Das Neue der Erfindung ist darin zu sehen, daß durch eine gleichzeitig als Abschaber dienende Vorrichtung die Heißluftventile der Trockenwalzen periodisch geöffnet ürid geschlossen werden. Die heiße Trockenluft wird somit dem _ Trockengut zwischen den Walzen in allen Höhenlagen des Schachtes gleichmäßig zugeführt, und zugleich werden. die von dem Trockengut ausströmenden feuchten Dämpfe wiederum in allen Höhenlagen überall gleichmäßig aufgenommen. In_ den Zeichnungen ist ein Ausführungsbeispiel gemäß der Erfindung dargestellt. Die Abb. i, 2 und 3 sind die Schnitte durch den Trockenofen; Abb. 4. zeigt den Schaber mit Ventilbetätigung in vergrößertem Maßstabe.The novelty of the invention is to be seen in the fact that by one at the same time as a scraper device the hot air valves of the drying rollers periodically open or closed. The hot dry air thus becomes the _ dry material evenly fed between the rollers at all heights of the shaft, and become at the same time. the moist vapors flowing out of the dry material in turn recorded uniformly everywhere at all altitudes. In_ the drawings is an embodiment shown according to the invention. Figs. I, 2 and 3 are the sections through the Drying oven; Fig. 4. shows the scraper with valve actuation on an enlarged scale.
Die Arbeitsweise ist folgende: Den einzelnen Trockenwalzen e wird durch die gegenüber dem Vorgelege d befindlichen hohlen Drehzapfen c die Heißluft unter Druck zugeführt, so daß sie bei jeder Umdrehung durch die am anderen Walzenende vermittels des Abschabers betätigte Ventil in in den Trockenschacht eintreten kann, und zwar in der Menge, als zum Trocknen des Gutes und zur Aufnahme der Feuchtigkeit notwendig ist.The method of operation is as follows: The individual drying rollers are e the hot air through the hollow pivot pins c located opposite the intermediate gear mechanism d fed under pressure so that it passes through the one at the other end of the roll with each revolution valve actuated by means of the scraper can enter the drying shaft, in the amount needed to dry the goods and absorb the moisture necessary is.
Die in allen Höhenlagen des Trockenschachtes sich ständig vermischende Trockenluft mit der aus dem Trockengut entströmenden Feuchtigkeit wird je nach Bedarf mittels Saugvorrichtung aus dem Trockenschacht abgeführt, so daß das Trockengut auf seinem Wege über die heißen Trockenwalzen seinen Feuchtigkeitsgehalt verlieren muß, ohne daß es an irgendeiner Walze festbacken kann, weil die Abschaber jedes Anhaften des Trockenguts auf den Trockenwalzen, unbeschadet ihrer ersten Aufgabe, -die Heißluftventile zu öffnen und schließen, verhindern. Der Trockenofen wird zweckmäßig mit einer Außenkammer a umgeben, welche auf der einen Seite die Zuflußrohre c für die Heißluftspeisung, auf der anderen Seite den Vorgelegsantrieb d aufnimmt. In den Vorderurid Rückwänden sind gegebenenfalls Fenster zur Beobachtung des Trockenvorganges eingebaut.The constantly mixing at all altitudes of the dry shaft Dry air with the moisture flowing out of the dry material is used as required discharged from the drying shaft by means of a suction device, so that the material to be dried lose their moisture content on their way over the hot drying rollers must without it sticking to any roller, because the scrapers each The dry material adheres to the drying rollers, regardless of their first task, -Prevent the hot air valves from opening and closing. The drying oven becomes appropriate surrounded by an outer chamber a, which on the one hand, the supply pipes c for the hot air supply, on the other hand the countershaft drive takes up d. In the front urid rear walls may be windows for observing the drying process built-in.
Die Trockenwalzen können aus beliebigem Metall oder aus Porzellan bzw. Steingut hergestellt werden. Sie werden an den Kopfenden mit gekröpfter Nabe abgeschlossen. In einem der Hohlzapfen befindet sich die Zuflußdüse für die Heißluft, auf dem anderen ist die von außen einwirkende Antriebsvorrichtung angebracht. Das Heißluftausströmungsventil ist in den Oberflächenteil der Trockenwalzen (Abb. q.) so in die Wandung eingesetzt, daß es von der Gleitschiene o des in der Schachtwand befestigten Abschabers durch Niederdrücken eines halbrunden Ventilkopfes geöffnet wird und sich nach kurzer Entströmung von heißer Luft vermittels Federzugs selbsttätig schließt. Das von oben mittels Transportbands f in den Trockenschacht geleitete Trockengut wird unten durch die Abflußleitung i in die bereitstehenden Behälter e weiterbefördert.The drying rollers can be made of any metal or porcelain or earthenware are produced. They are cranked at the head ends closed. The inflow nozzle for the hot air is located in one of the hollow pegs, the drive device acting from the outside is mounted on the other. That Hot air outflow valve is in the surface part of the drying rollers (Fig.q.) so inserted into the wall that it is from the slide rail o the in the shaft wall attached scraper opened by pressing down a semicircular valve head and automatically after a short outflow of hot air by means of a spring balancer closes. The one that is fed into the drying shaft from above by means of a conveyor belt f Dry material is at the bottom through the drainage line i into the prepared container e promoted.
